The results of a swim meet are shown. Who swam the fastest? Explain your reasoning.
kobusy [5.1K]

Answer : The Susana swam the fastest.

Step-by-step explanation :

Speed : It is defined as the distance traveled per unit time.

Formula used :

Speed=\frac{Distance}{Time}

First we have to determine speed of the following persons.

<u>For Tawni :</u>

Distance = 50 m

Time = 40.8 s

Speed=\frac{Distance}{Time}=\frac{50m}{40.8s}=1.225m/s

The speed of Tawni is, 1.225 m/s

<u>For Pepita :</u>

Distance = 100 m

Time = 60.2 s

Speed=\frac{Distance}{Time}=\frac{100m}{60.2s}=1.661m/s

The speed of Pepita is, 1.661 m/s

<u>For Susana :</u>

Distance = 200 m

Time = 112.4 s

Speed=\frac{Distance}{Time}=\frac{200m}{112.4s}=1.779m/s

The speed of Susana is, 1.779 m/s

From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.

Thus, Susana swam the fastest.

4. I need help with question in the attached picture!
Arisa [49]

ANSWER

D. 13

EXPLANATION

We have

f(x) =  \frac{2x + 1}{x - 4}

To find

{f}^{ - 1} (3)

means we want to find an x-value whose image is 3.

\frac{2x + 1}{x - 4}  = 3

We cross multiply,

2x + 1 = 3(x - 4)

Expand:

2x + 1 = 3x - 12

Combine like terms,

3x - 2x = 12 + 1

x = 13

\therefore{f}^{ - 1} (3)= 13
